The A-weighted sound pressure emitted by this product is below 70 dB.

** The noise level can vary depending on the site.

The figures quoted are emission level and are not necessarily safe working levels.

Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not furtherprecautions are required.

Factor that influence the actual level of exposure of the workforce include the characteristics of the work room and the other sources of noise, i.e.the number of equipment and other adjacent processes and the length of time for which an operator exposed to the noise. Also, the permissibleexposure level can vary from country to country.

This information, however, will enable the user of the equipment to make a better evaluation of the hazard and risk.
